I read a post today on David Meerman Scott's blog Webinknow. If you're selling your books on Amazon, then you must read this post:
I was not aware of the program called AmazonConnect and it looks like something every author should be doing if your books are listed on Amazon.com. And, if you already have a blog then you're way ahead of the game. You can create an Amazon.com blog, connect the feed from your current blog to the Amazon blog and your posts can be linked to show up on your product pages. How cool is that???
Yet another way to build relationships with your audience and ultimately sell more books.
NOTE: It does appear that you must be an author whose books are being sold on Amazon.com in order to set up the AmazonConnect account and set up the blog.
